Abstract

Designing car audio that fits user’s needs is a fun activity. However, the design often consumes more time and costly since it should be consulted to the experts several times. For easy access to information in designing a car audio system as well as error prevention, an car audio system based on expert system and web is designed for those who do not have sufficient time and expense to consult directly to experts. This system consists of tutorial modules designed using the HyperText Preprocessor (PHP) and MySQL as database. This car audio system design is evaluated uses black box testing method which focuses on the functional needs of the application. Tests are performed by providing inputs and produce outputs corresponding to the function of each module. The test results prove the correspondence between input and output, which means that the program meet the initial goals of the design.

Abstract

Insufficient electricity supply in Java, Indonesia, has become an critical problem to be dealt by the goverment. One solution campaigned by the government is using electricity effectively by turning off unused devices that waste electricity. To make this action as a routine needs a reminder that can help remind people continually. One example of a reminder is an automatic static sensor which is already applied in some places. Dynamic sensor is one of best method to save energy because it can warn the user to turn off unused lamps. Dynamic sensor is also called moving sensor because it is able to move from a place to another and has a wide service area. This study gives information about the use of moving sensor in some areas in order to save electricity energy. As a pilot project, the use of moving sensor needs to be improved by a further study.

Abstract

Various constraints related to the availability of up-to-date information services and product sales happen to ProPoster Indonesia, a business of digital printing and display services system run since 2002. ProPoster Indonesia needs to offer an easy access to services and online service sales of printing products to its customers and plans to expand its business services throughout Indonesia. These conditions initiate the development of web-based service and products sales system for ProPoster Indonesia. The main objectives are to overcome the difficulties in obtaining the latest information related to services and products and facilitate promotional printing services to all parts of Indonesia. The sequential linear process model is used to develop the overall system while literature study is done to enrich the insight to develop a better system. The user friendly system makes easy for customers to get the latest information that ultimately facilitate the service process and product sales.

Abstract

English proficiency can be measured through several tests that are recognized internationally like TOEFL. To measure the English proficiency of ‘Binusians’ with TOEFL standards and provide rapid and credible test results, an program design of online English test application (ATBIO) is created by displaying a random question, in which every examinee gets different questions. Prior to the design, first performed profile analysis of the questions in the TOEFL test held by Binus University Language Center. Following is the design of the program using standard UML 2.0 notation. Furthermore, the author submitted the draft to be built by the program developers using java script or ASP. With credible, fast and accurate results of ATBIO, it is expected that people, departments or organizations concerned with these test results can immediately make decisions and take necessary actions.

Abstract

This research aims to help universities that do not have an academic information system and facilitate EPSBED data report to Directorate of Higher Education (DHE). The method used is the three first stages in the System Development Life Cycle (SDLC), which are systems engineering, requirements analysis, and design system. The result is a design of university business process, design of database, and design of user interface. This research finds that DHE has a specific data structure that can represent the basic activities of a study program. Therefore, this system design can be used for reporting of EPSBED data as well as for data collection of study program activities.

Abstract

Companies that have many applications always deal with application integration problems. For the of company necessity, they often yearn for information that an application can be used by other applications. Often a small portion of data from another application is needed in order to complete and support other business functions. They require an architectural approach that can bridge the information between applications. SOA (Service-Oriented Architecture) offers manufacturing services around existing business functions. Applications that wish to communicate with other applications can use the services to achieve business goals. This article will discuss recommendations and tips for implementing SOA best practices in banking.

Abstract

This study aims to analyze and design a migration and replication configurations in an enterprise using several methods such as literary study and direc survey to the company; analysis on hangar systems, process migration and replication as well as existing problems; and a prototype design for migration process implementated with Oracle SQL Developer and replication process implementated with Oracle GoldenGate. The study resluts ini a prototype for migration and replication configuration processes using Oracle's Golden Gate which can produce two sets of identical data for backup and recovery. Also a simple tool is designed to assist active-active replication process as well as active-passive one. The migration process from MySQL database to Oracle database using Oracle GoldenGate can not be done because GoldenGate Oracle has bugs related to the binary log, so database migration is done using Oracle SQL Developer. However, bi-directional replication between Oracle database using Oracle GoldenGate can ensure data availability and reduce the workload of primary database.
